All linux apps on my systems except netscape, vmware and acroread are updated by
me from src tarballs.  This system is an _old_ slackware distribution from
floppies many years ago that i've upgraded myself since the original install.
(no libc 5 cruft left on this system ;)

Guess it's time to learn CVS.

Thanks
